Finite phosphate: the low Cadmium and Uranium content mineral fertilizer resources already used up and in the future only contaminated resources are available.

Geopolitical risks: imported Phosphate is an critically important issue for the national security already now. All farmers need phosphorus, yet just 5 countries control 88% of the worlds remaining phosphate rock reserves.

An inefficient food system: large amount of P to waste streams, no recovery.

Cheap fertilizer: a thing of the past for farmers.

In the near future (2022) very drastic P price increase to come (In 2008 it was >700%).
